To all whom 'it ma concern: 9 f

Be it known t at I, WILLIAM' TAYLOR .Noam a citizen of theUnited States,-1resid ing at Elon College, in the county of Alamance and State of North Carohna,hav`e invented a new and useful Spindle-Driving f Mechanism, of which the following is ,a speci' ficat n.

This invention relates to spindle driving mechanism for spinning machinesof thati vgeneral class shown and 'described in United tates Letters Patent granted tome on the 17th da of Aug. 1897A under No. 588235.

. The o ljlect' of the invention is to improve the construction of thebolster and its associated parts and further'to-provide a novel form of step or bearing forfthe lower end of the spindle. y

A still further object is to generally im- 20 prove this class of devices so as to increase their utility, durability and eftlciency.

Furtherobjects and advantages appear in the followin description, it being understood that various changes in form,

*.125 proportions 'and minor details of construction may be resorted to Within the scope of the ap ended claims. J

ster at said openin and preferably formed integral therewith 1s a -cylindrical member or extension 12 the exterior walls of which are threaded, as indicated at 1 3.

Disposed within the cylindrical member 12 is a step 14 provided with a longitudinal bore 15 for the rece tion of the adjacent end 60 of the "spindle '16, tllielatter being provided with a conical terminal for engagement with a correspondingly shaped seat 17 formed in the base fof the step, as shown. The step -14 is rovided with spaced annular iianges or 65 dis 18 and 19 defining an intermediate chamber 20 for the reception of oil or other lubricant. Extendi transversely across the bottom of the cylindrical extension 12 is j a cap or closure 22 which is threaded for en- .70

gagementnwith .the threads 13 sothat the l cap maybe readily detached from the ex"- tension when it is desired to remove the step and spindle. The step 14 is provided with a y central depending lug or boss 23 ,and sur- 75 rounding said boss andinterposed between the ca 22 and the bottom of the step 14 is a yielda le gasketl or washer 24. The upper disk 19 vis spaced a short distance from the adjacent upper edge 25 of the extension 12 v80 thereby to form a cup 26 for the reception of a quantity of oil there being" anv opening 27 `formed in the disk 19 through'which the oil ."may pass from the cup 26 into the oil chama whirlor pulley 30 provided with an eXten-` 'f i sion`- or "collar 31.. which latter is welded,. .-9 5' shrunk or otherwise rigidly secured to the spindle so as to rotate with the latter. The Whirl 30 is disposed at the opening 11 and is f driven b a'rition disk o r driver 32 which -latter is eyed on an operating shaft 33 land 100` yieldably supported in engagement with the whirl by means of af coiled spring 34, The`v l friction disk 32 is provided withan annular ange' h'avingira.l seating-groove formed thereiin for the-reception of a gasket or cushion 36 '105,

which may b e formed of rubber, leather orally enga estthe periphery of the whirl, as shown.l he spindle 16 is centered with respect to the bolster by means of an upper bearing or gland 37 which enga es a corres ondingly shaped recess forme in the reuced extension 7 of said bolster. The whirl 30 is referably formed with an interior recess or the reception of the tubular body portion 41 of the step, Aas shown. 1t will thus be seen that when the oil or other lubricant is introduced in the cup 26, the latter Vwill flow through the openings 27 and 29 into vthe bore 18 and thus thoroughly -lubricate the bearing 17. It will also be observed that by removing the -cap 22 the step s indle and its associated parts may be withrawnl from the bolster through the threaded end of the latter, said cap not only forming a support for the step but also servi as a closure so as to eiectually exclude ntilde entrance of dust and dirt -tothe bearing.

.Having thus described the invention what is claimed is:

1. The combination with a bolster rail, of a bolster secured to the rail and having an opening formed in one side thereof, a step carried by the bolster, a s indle journaled in the step and provided wit a whirl disposed at the opening of the latter, and a cap secured to one end of the bolster and `forming a support for the step:

. 2. he combination with a bolster rail, of a bolster secured to said rail Aand having an opening formed in one side thereof, aste carried b the bolster and provided wit spaced disks forming an intermediate oil c amber, there being an opening formed in the upper disk and communicating with the oil chamber, a spindle journaled in the step and provided with a whirl disposed at said opemng, and a cap secured to one end of the' bolster and forming a support for the ste v3. The combination with a bolster rai of a bolster secured to the rail and having its lower end threaded and one side thereof provided with an openin a step dis osed within the bolster, a spinde journaledpin-the step and provided with a whirl disposed at the olppning in the bolster, a cap engaging the t eads on the bolster and forming a support for the step, and a washer interposed between the cap and step.

4.
